Biology

Shroomish is a small, mushroom-based Pokémon. Its upper body is peach-colored with green spots and a small opening at the top. Its lower body has frilled segments that overlap its green underside, which is round and has small, round feet. When it senses danger, it shakes its body and scatters toxic spores from the top of its head. These toxic spores can make trees and weeds wilt and cause whole body pain if inhaled. It lives in forests that are damp. It stays in the forest shade during the day, keeping still under fallen leaves. It eats composted soil in forests, which is made up of fallen, rotten leaves.

Shroomish appeared in Zoroark: Master of Illusions as a few of the many local Pokémon who lives in Crown City. A few of them worked with the other Pokémon in surrounding Zorua in the park to attack him, angry at Zorua for what Zoroark did to the city. Before a fight broke out, the Shroomish, along with the other Pokémon, were calmed by Celebi.
